I need to do more research into this area. People now ask me if I have a CD player before they give me a CD of their latest music. A lot of the younger generation don't have any physical playback systems at all, CD, vinyl, cassette etc. A lot of DJ equipment can now play wave and mp3 files. Any electronic parts I supply are invariably played back on a laptop as 24bit wave files. Things are definitely different now than they were even a few years ago.
